  1. Question 1

    Q1. A mechanic uses a wrench of length 50 cm to loosen a bolt by applying a perpendicular force of 20 N. Calculate the torque produced.

    • A) 10 Nm
    • B) 20 Nm
    • C) 5 Nm
    • D) 40 Nm

    Answer: 10 Nm

    Explanation: Torque is rF sin(90), so 0.5m times 20N equals 10 Nm. Option B fails because it ignores the 0.5m moment arm conversion.
